It is because when alleles show a co-dominant relationship , neither allele is dominant and both are expressed in the phenotype of the heterozygote. The human ABO blood groups provide a good example of codominace. The ABO system is due to a gene that codes for molecules on the surface of red blood cells

Explain why a coyote might be grouped into Level 3 in one food web and Level 4 in another.

Masteriza [31]

Answer:

This situation might happen depending on the ecosystem that it takes place in.

Explanation:

For example, in one ecosystem, where there are no serious predators trying to get the coyotes, they could be in a higher level because there is no immediate danger to them. However, in another ecosystem where there are predators trying to hunt them, they would be in a lower level because there, they are not at the top of the food web. Basically, it all depends on the ecosystem.

Hope this helps!

 All normal eggs from the mother have an X chromosome while usually half the sperm cells from the father have a Y (male) chromosome and the other half have an X (female) chromosome and it is therefore the father's sperm that dictates which gender the embryo will take.

If the egg is fertilized by a sperm with a Y chromosome then the embryo will be a genetic male due to XY chromosome combination.
If the egg is fertilized by a sperm with an X chromosome then of course the embryo will be a genetic female due to XX chromosome combination.
